Tumbler Screening Machine Involute Spiral Tumbler Sieve

 1500mm Tumbler Screening Machine Involute Spiral Tumbler Sieve

Overview of Tumbler Screeners:

  What is the tumbler screener? The tumbler screener is also called tumbler screen, tumbler screening machine, tumbler sieve, swinging screen, swinging sieve, rocking sieve, shaking sieve machine etc. The simplest sieving is using your hands with the staring of your eyes. Tumbler screening machine is the mechanical simulation for this.     

  Basically the movement of a tumbler screening machine can be compared to natural hand screening. For the control screening, fractionating and de-dusting of dry, powdered and granular products. Particularly suitable for high feed rates and multi-deck separations of fine, lightweight products which are difficult to screen.  

  Unlike a typical vibratory or gyratory screening machine, the tumbler screening machine incorporates a unique three-dimensional tumbling motion providing the gentlest screening possible. This motion prevents delicate, friable material from being broken resulting in less undesirable fine generation and dust levels. Even the most difficult materials, which tend to blind screens, are screened efficiently by utilizing the proper anti-blinding systems including motor driven brushes and/or air knives that are unique to tumbler type screening machines.

  The tumbler screening machines are used for bulk material grading, safety screening, and dedusting in all industrial sectors. They are particularly well-suited to the fine and extremely fine screening of dry bulk materials and precise grading with up to 6 particle sizes.

Working Principle of Tumbler Screeners:

   While the tumbler screening machine is running, its radial inclination ensures that the material being screened moves from the center of the screen outwards, while its tangential inclination makes the material move in circular fashion on the screen. The interaction between the two resulting forces makes the particles being screened move in a spiral pattern on the screen fabric, ensuring that the particles stay a long time on the screen. This, in turn, enables the machine to achieve an optimum level of grading accuracy with respect to the particle size ranges while simultaneously minimizing oversize and fines contamination.

   The movement of a tumbler screening machine is usually compared with simple hand screening. The product is continuously fed into the center of the top screen, from where it spreads out evenly to the outside across the entire screening surface. The finer particles fall through the screen near the center and the coarser ones successively towards the periphery. The material is moved in a spiral pattern with increasing acceleration of the particles the further they are from the centre, with the result that even those particles which are almost the same size as the screen mesh are screened. All the separated fractions are discharged through the lateral outlets. The screening process is repeated again and again on each deck.

Features of Tumbler Screeners:

1. High capacity: the unit area capacity is five times bigger than other screen machine.
2. High screening accuracy: it can imitate the screening action and process of manual operation effectively. Make the material walk a long distance on the screen surface, improve the screening accuracy.
3. Ingenuity: circular building block assembly structure, small volume, light weight. Easy to install and disassemble.
4. Long service life: low frequency, small load, so low load to the screen, can be used for long time.
5. No environment pollution: fully closed structure,almost no Let out of material dust.
6. It can add many kinds of the self-cleaning device to the screen surface which can avoid blocking the screen. There are five kinds of self-cleaning device for you to choose: bouncing ball,Rolls brushes,jet type,elastic scraper,ultrasonic.
7. Low noise: noise < 75db
8. Adopt brand motor as power source, with longer service life.
